All changes to the repository which affect the runtime environment(installed jupyter kernel, Conda's environment.yml, Pip's requirements.txt ) require a rebuild of the underlying Docker image of your profile.

Such a rebuild needs to be triggered manually by the profile manager and can be achieved by following these steps:

Step 1
Check if you have the manager role for your profile by using whoami. 

Ensure that you are a member of a group named: manager-{profile_slug}

Step 2
Navigate to the Profile service. 

Step 3
Select your profile from the drop-down menu.

Step 4
Press the button TRIGGER BUILD OF NEW DOCKER IMAGE.
